Hi, hope you're well.
I have been attempting to find a way to carry out an overidentification
test ("estat overid") of instrumental variable ordered probit regressions
(IV oprobit).
I am not sure if anyone in the STATA list might know the gmm commands to do
this. I have used the -cmp- commands, but as many of you know, there is no
overidentification test commands provided.
I would prefer having a gmm command rather than merely verifying it through
-ivreg2- that assumes linearity.
Thank you for your time on this.
warmest,
